Purpose: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. Methods: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. Results: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. Conclusion: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

For the rapidly growing elderly population, the achievement and maintenance of good nutritional status is critical to health, functioning and quality of life. Elderly women living alone have been identified as a group associated with poor nutrition. The purpose of this study was to assess dietary intakes of elderly women living alone as compared to those of elderly women living with family in a rural area and to examine seasonal variation. The subjects are 49 elderly women living alone and 41 elderly women living with family who reside in Goryeong-gun, Gyeongbuk, and their food intakes were assessed once each time in summer 2005, winter 2005-2006, and spring 2006. The average ages were 74.7 years for living alone and 72.8 years for living with family. Education level was not different between the two groups. Height, weight, body mass index, systolic and diastolic blood pressures, and fasting blood glucose were not significantly different between the two groups. Average intakes of major nutrients, nutrient adequacy ratio, mean adequacy ratio and index of nutritional quality were lower in the elderly women living alone compared with the elderly women living with family in summer, but the differences in intakes of most nutrients became insignificant both in winter and in spring. High carbohydrate and low fat diet was prevalent and intakes of carbohydrate and fat in summer deviated from macronutrient acceptable distribution ranges. Percentages of the subjects who consumed energy less than 75% of the estimated energy requirement and nutrients less than the estimated average requirement were higher than those reported by the Third National Health and Nutrition Examination Survey. In summer, the percentage of the subjects who consumed energy less than both 75% of the estimated energy requirement and 4 nutrients less than estimated average requirements was 58.5% of the elderly women living alone, which was higher than 26.5% of the elderly women living with family and that of National Nutrition Survey. Therefore, nutrition policies including nutrition education and support are necessary to improve nutritional status of elderly, especially elderly women living alone and should reflect regional and seasonal characteristics.

The aim of this study was to investigate the relationships among energy intakes, macronutrient intakes, macronutrient compositions, anthropometric and biochemical variables in natural environment of free-living female college students. The daily energy and macronutricnt intakes were analyzed by means of 3- week dictary records. The waist circumference and insulin level were best anthropometric and bio-chemical correlates with the energy, carbohydrate and protein intakes respectively. However, there were no relationships between waist circumference and insulin verse macronutrient compositions that macro-nutrient intakes were expressed as by the percentage of daily encrgy intakes. There were no relationships between BWI, weight, perccnt body fat and fat mass vs. energy and macronutrient intakes. However, BMI was positively related to the percentage of energy from fat and inversely related to the percentage of energy from carbohydrate in their habitual diet. Triglyceride was negatively correlated to the per-centage of energy from fat and fat intakes. Significant positive correlation was also observed bctween the percentage of energy from protein and HSL-cholcsterol.

Objective : Obesity is an important cause of diabetes, and lipotoxicity causes insulin resistance. Recently a lot of research is being done on PPAR-${\alpha}$. TNF-${\alpha}$. adiponectin, and leptin, which are important obesity related factors. In this study, we investigated the effects of Supungsunki-hwan on high fat. high carbohydrate diet-induced obese type 2 diabetic mouse models. Methods: Diabetes was induced in ICR male mouse (30${\pm}$5g) with Surwit's high fat, high sucrose diet. Mice were divided into 4 groups(n=10) of Normal. Control. Supungsunkj-hwan group. and acarbose group. The Supungsunki-hwsn group was given 10% Supungsunkj-hwan in their diet. and the acarbose group was given 0.5% acarbose in their diet. After 6 weeks. body weight. food intake, FBS and OGTT. lipid profile and liver enzymes, epididymal fat weight, and gene expression of leptin, adiponectin, TNF-${\alpha}$ and PPAR-${\alpha}$ were measured. Leptin. adiponectin. tumor necrosis factor(TNF)-${\alpha}$ and peroxisome proliferator-activated receptor (PPAR)-${\alpha}$ were evaluated by reverse transcription-polymerase chain reaction. Results : Supungsunkj-hwan increased the gene expression of PPAR-${\alpha}$, which reduces lipotoxicity and insulin resistance. Supungsunkj-hwan also significantly reduced triglyceride. AST. ALT serum levels. and 1 hour oral glucose tolerance levels. Conclusion : These results show that Supungsunkj-hwan improves insulin resistance in the liver and muscles, by reducing triglyceride levels and lipotoxicity through increased PPAR-${\alpha}$ gene expression. This is supported by the fact that Supungsunkj-hwan significantly reduces 1 hour oral glucose tolerance levels. Therefore we suggest that Supungsunkj-hwan would be an effective treatment for obese type 2 diabetic patients.

The purpose of this study was to provide a descriptive assessment of the nutritional habits of resistance trained males in relation to protein and carbohydrate intakes in comparison with the recommended values. Thirty-four male bodybuilders ($27.0{\pm}2.1years,\;173.5{\pm}5.0cm,\;8.3{\pm}0.61%$ body fat), twenty-four male weight lifters ($20.9{\pm}2.1years,\;171.8{\pm}6.9cm,\;7.6{\pm}0.98%$ body fat) and twenty-five male non-athletes ($26.9{\pm}2.5years,\;175.3{\pm}5.7cm,\;8.5{\pm}0.95%$ body fat) participated in the study. Participants completed a comprehensive survey by twenty-four hour dietary recall methods. All diets were analyzed using the Computer Aided Nutritional (Pro) analyzer by a registered dietician. Body fat was measured using skin fold thickness. The average time spent in resistance training was $18.0{\pm}1.7$ hrs/week for body builders and $14.6{\pm}8.7$ hrs/week for weight lifters. Total daily calories were $2583.6{\pm}874.8kcal\;(31.9{\pm}11.9kcal/kg)$ for bodybuilders, $3565.9{\pm}1281.8kcal\;(42.7{\pm}15.0kcal/kg)$ for weight lifters and $2016.0{\pm}955.3kcal\;(28.1{\pm}13.9kcal/kg)$ for non-athletes (p=0.001). Percent of calories from carbohydrate, protein, and fat 64.2%, 27.1%, and 8.7% for bodybuilders, and 66.3%, 18.6%, and 15.1% for weight lifters. The mean protein intake was $1.9{\pm}1.2g/kg$ of BW for bodybuilders, $1.6{\pm}0.6g/kg$ of BW for male weight lifters and $1.1{\pm}0.69g/kg$ of BW for non-athletes. Although dietary calcium (78.7%) and riboflavin (86.3%) intakes for bodybuilders were below the RDA, dietary intakes of micronutrients were not deficient. More research needs to be conducted to determine the optimal amounts of protein, carbohydrates, fats, and micronutrients for the resistance trained athletes.

Thailand is becoming an aging society, this presenting as a serious problem situation especially regarding health. Chronic diseases found frequently in the elderly may be related to dietary intake and life style. Surin province has been reported as a risk area for liver fluke with a high incidence of cholangiocarcinma especially in the elderly. Therefore, this study aimed to determine the nutritional status and associated factors among elderly in Surin province, northeast of Thailand. A community-based cross-sectional study was conducted among 405 people aged 60 years and above, between September 2012 and July 2014. The participants were selected through a randomized systematic sampling method and completed a pre-designed questionnaire with general information, food recorded, weight, height, waist circumference, and behavior regarding to food consume related to liver fluke infection. The data were analyzed using descriptive statistics and Spearman's rank correlation coefficients. The majority of participants was female (63.5%), age between 60-70 years old (75.6%), with elementary school education (96.6%), living with their (78.9%), and having underlying diseases (38.3%). Carbohydrate (95.3%) was need to improve the consumption. The participants demonstrated under-nutrition (24.4%), over-nutrition (16.4%), and obesity (15.4%). Elderly had a waist circumference as the higher than normal level (34.0%). Gender, female, age 71-80 years old, elementary school and underlying diseases were significantly associated with poor nutritional status. The majority of them had a high knowledge (43.0%), moderate attitude (44.4%), and moderate practice (46.2%) regarding food consumption related to liver fluke infection. In conclusion, these findings data indicated that elderly age group often have an under- or over-nutritional status. Carbohydrate consumption needs to be improved. Some elderly show behavior regarding food consumption that is related to liver fluke infection hat needs to be improved, so that health education pertaining good nutrition is required.

The purpose of this study was to investigate the effect of dietary zinc levels on carbohydrate metabolism and serum zinc, magnesium and chromium contents in obese rats. Animals were divided into three groups by zinc levels, such as low (15 ppm), adequate (30 ppm) and high (60 ppm) levels of dietary zinc. The food intake, weight gain and feed efficiency ratio were not changed by zinc levels. There were no significant differences in liver, kidney and spleen weights. However, serum glucose concentration significantly decreased as the levels of dietary zinc increased, in particular, that of obese rats fed the high level of zinc was remarkably decreased. Insulin concentration of rats fed high level of zinc diet was significantly higher than that in the other groups. However, there were no significant differences in serum zinc and chromium contents, although serum magnesium fed zinc deficient diet was significantly higher than that of the other two groups. Glucose concentrations had negative correlation with insulin concentrations, and positive correlations with serum magnesium content. In conclusion, serum glucose concentrations were decreased and insulin concentrations were increased as the levels of dietary zinc increased in obese rats. These results suggested that zinc supplement at higher level than adequate one would increase insulin concentration and may improve hyperglycemia problem in obese groups.

Food neophobia, unwillingness to try novel foods, is a personality trait that can influence children's food preferences and consequently their food acceptance and consumption. The purpose of this study was to determine whether children with food neophobia have poor dietary and growth outcomes compared to non-neophobic children. Subjects were 332 primary school children from 6 randomly selected schools in the district of Hulu Selangor, Selangor. Parents and children were interviewed to obtain demographic, socio-economic, food neophobia and dietary intake information. The children were also measured for weights and heights. One-way ANOVA and Chi-square procedures were utilized for statistical data analysis. Children with food neophobia had higher intakes of energy and most nutrients than average and neophilic children. However, only the mean intakes of protein (p < 0.05) , fat (p < 0.05), vitamin A (p < 0.01) and iron (p < 0.01) were significantly higher in neophobic than average or neophilic children. Compared to neophilic and average groups, a higher percentage of neophobic children met 2/3 of the RNIs for energy $(85.2\%)$, protein $(98.4\%)$ and vitamin A $(72.1\%)$. Mean percentage of carbohydrate energy was lowest$(54.8\pm6.6\%)$ while fat energy $(31.8\pm6.2\%)$ was highest among neophobic children. Neophobic group had the lowest percentage of children $(49.2\%)$ with carbohydrate energy > $55\%$ but highest percentage $(50.8\%)$ with fat energy > $30\%$. For the three study groups, the mean number of servings for all food groups, except grain and cereal, did not meet the Food Pyramid recommendations. Neophobic children consumed significantly more numbers of servings from the meat group than average and neophilic groups (p < 0.01). All study groups had relatively low mean dietary diversity scores but neophobic children had the lowest score $(0.67\pm0.73)$ compared to the average $(0.97\pm0.72)$ and neophilic $(1.98\pm0.81)$ groups. Significant difference in mean dietary diversity scores were only observed between neophobic and neophilic children (p<0.05). Higher percentages of neo-phobic children had low weight-for-height and were at-risk of overweight(p < 0.05). Nutrition practitioners need to understand children's food preferences in their efforts to promote healthful diets for children. To improve children's eating behaviors, parents may need the guidance and support from nutritionists and dietitians that are specific to their needs and their child's situation.

The purpose of this study was to evaluate nutrients intakes, glycemic index (GI), glycemic load (GL) according to obesity index in elementary school students. The study subjects included 229 elementary school students (boys=108, girls=121) who were divided into 3 groups consisting of an underweight group (obesity index<-10%, n=58), a normal weight group (10%${\leq}$ obesity index<10%, n=130) and an overweight group (obesity index${\geq}$10%, n=41) by their obesity index. The nutrient and food intakes data obtained by a 3-day food record were analyzed. Daily dietary GI and GL values were calculated from the 3-day food record. The average age of the subjects was 11.9 years. The mean daily energy intake was 2,186.8 kcal in the underweight group, 2,123.5 kcal in the normal weight group, and 2,174.2 kcal in the overweight group. The intakes of calcium and animal calcium per 1,000 kcal in the overweight group were significantly lower than in the underweight and normal weight groups (p<0.01, p<0.05), and fruit, egg and milk intakes in the overweight group were lower than those in the underweight group (p<0.05, p<0.05, p<0.05). The mean daily dietary GI of the underweight, normal weight, and overweight groups were 67.7, 68.4 and 69.5, respectively (p<0.05). The mean daily dietary GL of the underweight, normal weight, and overweight groups were 212.8, 208.1 and 213.3, respectively. The major food source of dietary GI and GL in the three groups was rice. Other major food sources of dietary GI were croquettes, hand-rolled noddle soups, instant noddles, milk, and rice cake. Dietary GI was not significantly correlated with weight, obesity or body mass index, when adjusted for energy, carbohydrate, and dietary fiber. However, GL adjusted to energy, carbohydrate and dietary fiber tended to correlate with obesity index (r=0.126, p=0.059). These results suggest that dietary GI and GL have possibility affecting obesity-related indicators in elementary school students.

This study was conducted to evaluate the dietary quality of school-aged children from low-income families in comparison with those from higher income families. The socio-demographic and anthropometric data and one day 24-hour recall dietary intake data of 1,782 school-aged children were used for analysis from the data of 2001 National Health and Nutrition Survey. The children whose family had monthly household income 120% or lower than the 2001 Minimum Cost of Living were classified into Low Income Group (LIG), and the others were classified into Higher Income Group (HIG). The consumption levels of the food groups of the Korean Food Guide as well as the general nutritional status based on their weight and height, energy and nutrient intake were compared between LIG and HIG in elementary (n = 989), middle (n = 432), and high (n = 361) school-aged children, respectively. LIG tended to have lower weight, height, and BMI than HIG, but the difference was significant only in the weight and the BMI of the middle school-aged children. The energy intake of LIG didn't differ from that of HIG, but LIG consumed a higher percentage of energy from carbohydrate and a lower percentage of energy from fat than HIG. Some micronutrient intake was lower in LIG than HIG in case of the elementary and the middle school-aged children. The average numbers of servings of milk dairy products and fruits consumed by LIG were significantly lower than those consumed by HIG in the elementary and the middle school-aged children, and they were less than the respective recommended serving. The average number of servings of meat fish egg beans consumed by LIG was lower than that consumed by HIG in the middle and the high school-aged children, and it was also less than the recommended serving. The results suggested that the diet of children from low-income families should be intervened by strategies different from the other children in order to improve the consumption level of milk dairy products, fruits, and meat fish egg beans.
